摘要： PROBLEM TO BE SOLVED: To obtain a fuel gas for fuel cells which does not poison an electrode catalyst and electrolyte of the fuel cell and is easily detected when the gas is leaked. SOLUTION: An odorant which does not poison the electrode catalyst and electrolyte and loses odor 1 when dissolved in water is added to the fuel gas for fuel cells. As the odorant, a fatty acid such as acetic acid, butyric acid and the like are cited. Thus, an odor is added to the fuel gas without poisoning the electrode catalyst and electrolyte of the fuel cell and with leaving no odor in an exhausted gas from the fuel cell.

摘要： PROBLEM TO BE SOLVED: To provide a cell voltage monitor part structure of a fuel cell in which a contact failure or loose-fit between a cell voltage monitor member and a separator of the cell does not occur and falling-off of the separator of the cell does not occur either. SOLUTION: (1) This structure is provided with the elastically deformable cell voltage monitor member 30 having a cell contact part 31 and a weight 32 for the cell voltage monitor member to press down the cell voltage monitor member 30. This is the cell voltage monitor part structure of the fuel cell in which the cell voltage monitor member 30 is pressed down at the cell contact part 31, in which the voltage monitor member 30 is pressed down by the weight 32 for the cell voltage monitor member, in which the cell voltage monitor member 30 is elastically deformed and in which the cell contact part 31 of the cell voltage monitor member 30 is pressed down to the cell so that the contact with the cell will not be loosened. (2) A depression 33 is installed at a site to which the cell contact part 31 of the cell is pressed down.

摘要： PROBLEM TO BE SOLVED: To further reduce the failure of the joined body of membrane electrodes in which two electrodes are clipped in electrolyte membranes and the failure of lamination of the separators which clip this membrane electrode joined body.
SOLUTION: Cut-out parts 42, 44 and 46 of inclined shape are provided at the corner of the rectangular-plate membrane electrode joined body 28 and the separators 30, 32. When the membrane electrode joined body 28 and the separators 30, 32 are laminated in a wrong direction, the cut-out parts 42, 44 and 46 do not match each other, thereby the correctness of lamination can be judged easily by appearance during lamination or after lamination. Hence, the failure of lamination can be further reduced.

摘要： PROBLEM TO BE SOLVED: To provide a sunlight condensing device which is capable of coping a with wide-range irradiation angles for high-efficiency condensation, when reflection and total reflection are utilized with a prism. SOLUTION: A light guide plate 1 comprises first and second prisms 2 and 3. The first and second prisms 2 and 3 comprise the media of refractive indexes which differ from each other. A backside 3a of the second prism 3 is provided with a mirror 4. The light incident on the light guide plate 1 refracts at an interface K0 while advancing inside the light guide plate 1, satisfies total reflection condition as the incident angle at an interface K5 to air at the first prism 2. As a result, the light advancing inside the light-guiding plate 1 is guided into a solar cell without transmitting to the outside, for improved light- condensing efficiency.

摘要： PROBLEM TO BE SOLVED: To provide a water electrolyzing anode low in oxygen overvoltage and high in durability by forming the anode from the activated carbon and electrode material in contact with each other. SOLUTION: The Ni, Co, Ag, etc., low in oxygen overvoltage is preferably used as the electrode material. Any kind of activated carbon can be used, the fiber of activated carbon is put between meshy electrode materials, or the plates are placed on one another. Concretely, the activated-carbon fiber 1 is put between the electrode-material meshes 2 made of nickel to obtain an anode. The water decomposing voltage is lowered close to the theoretical value by using this anode. Further, the electrode material is brought into contact with the activated carbon through silicon carbide or boron carbide to improve the durability of the anode. Actually, the activated carbon coated with the film of silicon carbide or boron carbide by sputtering, etc., is brought into contact with the electrode material.

摘要： PURPOSE: To miniaturize and lighten a condensing solar cell device to generate a full generating power. CONSTITUTION: Four solar cells 2 for movement are provided on the periphery of a solar cell 1 for generation. Electromagnets 21, which are respectively connected with these cells 2, are provided under the cells 2 and at the same time, the cell 1, the cells 2 and the electromagnets 21 are installed on a cell support 14. Moreover, a permanent magnet 26 on a ring is arranged on the periphery of the cell 1. When a condensing spot 13 is shifted by a condensing lens 11, light strikes on some one of the cells, whereby a current is made to flow through the electromagnet 21, which corresponds to the cell 2 struck with the light, and the electromagnet 21 and the magnet 26 attract to each other to move the support 14. When the spot 13 is returned on the cell 1, a generation is stopped due to the cells 2 and the movement of the support 14 is stopped.

摘要： PURPOSE:To provide the liquid crystal optical element which enables uniform control of liquid crystal molecules, solves the problem of scattering of incident light and is variable in focal length or irradiation angle. CONSTITUTION:This liquid crystal optical element consists of a liquid crystal cell formed by holding a liquid crystal layer 3 having a uniform thickness between a lens substrate 1 and a flat plate glass substrate 2. The liquid crystal molecules are oriented in a direction parallel with the substrate surface and symmetrically in correspondence to the optical symmetry of the lens on the substrate 1 side. The liquid crystal molecules are oriented in a direction parallel with the substrate surface on the other substrate 2 side and in a direction perpendicular to the orientation direction of the liquid crystal molecules on the substrate 1 side. The thickness of the liquid crystal layer 3 is set small within a range where the liquid crystal layer 3 does not exhibit an optically rotary characteristic. The liquid crystal layer 3 exhibits a convex lens or concave lens function with the incident light polarized in a prescribed direction.
